Eliminates Wobbling & Chatter - the final straighten process is added. which keep the bit in a straight line during rotation and reduce chatter;

Designed- these bits with a split point keep centered without a pilot hole, full-ground body drill faster with fewer defects. excellent chip removal and heat removal;

Hex shank drill bit set classic construction with titanium coating for capability and durability.The cutting edge is hardened and honed for sharpness, chatter-free design with staggered cutting teeth ensure the precise countersinking and hole smooth clean.
